Hi,

I have been looking at hunspell git repo, 

https://github.com/hunspell/hunspell

That string is defined in src/tools/hunspell.cxx file (line 60,
HUNSPELL_PIPE_HEADING) and seems to still be there. No changes in it
since end of last January, and they were only formatting changes.

With hunspell-1.4.1 in Debian GNU/Linux (note that 1.4.0 version is wrong),

$ hunspell -vv < /dev/null
@(#) International Ispell Version 3.2.06 (but really Hunspell 1.4.0)

$ hunspell -a < /dev/null
@(#) International Ispell Version 3.2.06 (but really Hunspell 1.4.0)

Although by the way,

$ hunspell -va < /dev/null
Hunspell 1.4.0
$ hunspell -vva < /dev/null
Hunspell 1.4.0

Where does your hunspell come from?

Regards,
